Why is formula of water H2O?

Answer 1

the h stands for hydrogen and the 2 means there are 2 hydrogen and the o means there is 1 oxygen.... basically its the formula for water because water is made of 2 hydrogen atoms and 1 oxygen atom

Answer 2

In almost every case you have to put the cation (positively charged ion) first. In the case of water the H has a charge of +1. The oxygen has a charge of -2. Therefore we must name water with H first.

Answer 3

H2O has 2 moles of Hydrogen and 1 mole of oxygen.

2HO has 2 moles Hydrogen and 2 moles oxygen.

The 2 in H2O is usually a subscript which corresponds only to the element/ion before it, in this case, H.

The 2 in 2HO is called a numerical coefficient which corresponds to the whole compound after it.

Answer 4

The formula of water is H2O because each water molecule is composed of two hydrogen atoms bonded to one oxygen atom. This combination allows water to maintain a stable structure and form hydrogen bonds.

Answer 5

no
